Libtmux

Improvement

- `fetch_objs` now raises `ObjectDoesNotExist` with detailed information on
lookup that failed (466)

Fixes

- Server: Launching of new session with default socket (857)

Fixes

- Window.panes: Fix docstring

Breaking

- Server: Add `__repr__` and set `socket_path` if none set.

Before (0.17 and below):

python
<libtmux.server.Server object at ...>


New `__repr__` (0.18+):

python
Server(socket_name=test)


python
Server(socket_path=/tmp/tmux-1000/default)

- Server: Move `_list_panes` and `_update_panes` to deprecated

Fixes

- Documentation fixes
- Add deprecation warning to `Server.children`, `Session.children`,
`Window.children`.
